2.8. Hard Drive Installation
NOTE
:
Your hard drives have been preintegrated in drive trays and
replacement hard drives will come preintegrated as well. The following
procedures apply to the cases where you may have to replace or sway
hard drives for troubleshooting purposes. Always replace hard drives
with the exact size and model of the original drive.
2.8.1 Hard Drive Installation Prerequisites
Hard drives for the GALAXY subsystem must be purchased separately.
When purchasing the hard drives, the following factors should be
considered:
Capacity (MB/GB):
Use drives with the same capacity. RAID arrays use a
“least-common-denominator” approach. The maximum capacity of each
drive used in the array is the maximum capacity of the smallest drive.
Choose big drives with the same storage capacity.
Profile:
The drive trays and bays of the system are designed for 3.5-inch
wide x 1-inch-high hard drives. It is highly recommended that you do not try
to use drives of any other size.
Drive type:
The GALAXY described in this manual can use SATA-II or
SATA-I hard drives. Please ensure that you purchase the correct hard drives.
CAUTION!
The hard drives and drive trays should only be installed into the
subsystem after the subsystem has been mounted into a rack cabinet. If
the hard drives are installed first, the subsystem will be too heavy to lift
and the possible impact during installation may damage your drives.
WARNING!
1.
Handle hard drives with extreme care. Hard drives are very
delicate. Dropping a drive onto a hard surface (even from a short
distance) and hitting or touching the circuits on the drives with your
tools may cause damage to the drives.
2.
Observe all ESD prevention methods when installing drives.
3.
Only use screws supplied with the drive canisters. Longer screws
may damage the drive.
